Analyst · Cowen & Company. Your line is open
Thank you, Jason, and welcome everyone. I appreciate your time this afternoon. I just want to give a very brief synopsis of the company and what we do. For those listeners that would be encountering this call for the first time, first and foremost you should recall that KemPharm’s technology is designed, reengineered previously approved products into new forms referred to as prodrugs. Those prodrugs once ingested or used as directed will then impart the therapeutic activity for that particular product. And highly successful organization at discovering and developing these particular prodrugs and currently have eight different products in our pipeline with a goal of submitting an NDA for each one of those products starting in '17 with at least one per year following that. We did receive some very welcome news this particular week with the granting of the Fast Track for KP511, one of our prodrugs that we’ll discuss in a little more detail later in the call. I would like to transition over and discuss a little more on Apadaz, as Jason mentioned. Apadaz is our lead product currently being reviewed by the FDA as well as sNDA and the potential for approval. It is a combination of benzhydrocodone and acetaminophen where benzhydrocodone is a prodrug of hydrocodone. For those that are aware, hydrocodone/acetaminophen combinations are the most prescribed opioid in the United States and represent what’s known as an immediate release profile or immediate release class of opioids typically used in acute pain. This particular prodrug of hydrocodone imparts abuse deterrent properties at the molecular level that being that in this particular instance there’s no additional formulation that was added but the prodrug itself only digest down to hydrocodone once taken as directed that is it would be orally. So other routes of abuse particularly intranasal and intravenous, the prodrug is inefficient or delayed and thus doesn’t create the same rewarding effects that we’ve seen in the past with combination products. Last week, many of you know that we had an advisory committee meeting on the particular product. Advisory committee meetings can be again an opportunity for the FDA to seek outside council on any particular issues related to the drug development, drug discovery, clinical data, whatever the FDA can need in this particular instance. Many times it’s advice seeking, so there can be votes associated with those but the votes are not binding to the agency and only help inform what their decisions may be. In a particular instance of our advisory committee meeting, we did receive a positive vote for approval but a negative vote for the abuse deterrent language that was added as a last minute question. We think that was of course unexpected because that vote wasn’t there in the previous briefing documents, and also the fact that it was negative was disappointing to the organization. The reason really why we’re discussing and focusing on this is we still believe very strongly in that Apadaz represents the first immediate release product that can potentially address abuse in this space that has no abuse deterrent products. While the data in this particular instance is related to the immediate release profile of a prodrug, we think in fact it does provide benefits above currently available products. Certainly, we’re in full agreement with both the FDA and the committee that it’s both safe and effective. We’ve demonstrated bioequivalence, so there seems to not be any confusion there. But there was some confusion both with the committee and the FDA related to some of the data on tampering and clinical studies that were done. It is our hope and intension to work closely with the FDA to clarify any potential confusion and work forward to next steps, which would be discussion of the label in this particular instance. To really briefly summarize where we are with the NDA, we have a target action date, a PDUFA date of June 9. So typically at this stage in drug development, you would expect to have interactions with the agency where in fact you’re now going to be negotiating the label, having final discussions around what that should look like and we hope those will be very interactive and collegial as they have been through the entire course of drug development of Apadaz. Next steps for this particular product, I really highlighted already here. One thing that we should note is the organizational experience we have with prodrugs. Certainly, this isn’t the first time we’ve encountered this level of confusion. I think there’s very reasonable approaches that you can take to help and recalibrate positions around what is a prodrug, how does it work, why is the tampering relevant or irrelevant, and what is the relevance of the clinical data? And again, those experiences belong to the organization with our past histories and our current histories with the products that we’re currently developing. So while we think there’s a really good path forward, we are by no means indicating that we know what that end result will be. Certainly that ultimate decision will still lie with the agency. Looking a little bit more forwardly beyond Apadaz, so thinking about KP511, our prodrug hydromorphone now for severe pain with an extended release profile. As I mentioned before, we did receive a Fast Track designation, the IND was accepted earlier this year as well. We have initiated clinical trials. That study is ongoing and we expect to have our first in man proof-of-concept data this quarter. So in the second quarter, we expect to have data back from that program. Depending on the results of that data, we have additional data looking at some of the abuse deterrent properties in the clinic later this year as well. If you may recall the key attributes that we’re really looking at for a product like KP511 are different than what we’ve seen with Apadaz. This is an extended release product as we develop it, not an immediate product like Apadaz. And the profile that we’re looking for here is similar when you think about intranasal and IV abuse, but additionally we’ve seen preclinical data that strongly suggest the potential to mitigate overdose and perhaps oral abuse as well as the potential to reduce opioid-induced constipation. Again, a much needed patient benefit for this potential product. The next product in our pipeline is KP201 immediate release without acetaminophen, so essentially an acetaminophen-free version of Apadaz. I think there was a very good feedback on the properties of the prodrug. As many of you know in this particular instance, acetaminophen actually creates a little bit of a burden for Apadaz in that it makes most of the dose that would be taken intranasally go down the back of the throat. We’ve seen very good indications in our study KP201/AO3 where we just look at the pharmacokinetics of this product, alone without the formulation now, just the benzhydrocodone itself and we see drastic differences in both liking and drug exposure. And we think that potential product has some tremendous advantages over even Apadaz, but certainly over current technologies. We’re still planning an IND submission this year. There will be additional clinical studies and clinical data that we’ll finish very rapidly after that. So we plan to file the NDA in 2017. As well this year, we will be working diligently towards KP415, our first foray outside of abuse deterrents. Now we’re focused on a prodrug of methylphenidate. This particular prodrug is designed to be very similar to Vyvanse and how it delivers its effectiveness to patients. So here we’re looking for a 13-hour duration of use and potentially being built under the label, as well as a robust pharmacokinetic profile that can deliver effective and reliable therapy, which as you can imagine would be very critical for treatment of ADHD. Next steps in our drug development would be IND submission this year as well as human proof-of-concept data late this year. So we expect this to happen in the second half for both of those milestones. Again, this has been again quite a year already for KemPharm and our potential products. Many of us know having been through this many times with different products, drug development is never a straight line. You usually have some twists and turns and I think we’ve encountered one of our very first with this particular product. Our goal is still ultimately to have a truly differentiated pipeline, develop those products and then either through commercial collaboration or commercial launch to take those products forward. So I’m going to turn the call over now to LaDuane Clifton who will give you a brief overview of KemPharm’s current finances. LaDuane?
